GS1 US® is a not-for-profit information standards organization. GS1 Standards are the most widely used supply chain standards in the world and support many regulatory compliance requirements across a variety of industries. Founded in 1973 and based in Ewing, New Jersey, GS1 US administers the Universal Product Code (UPC) barcode, as well as other information standards and data carriers. In this blog, Cait Platt at GS1 US will cover some of the basic barcode placement guidelines for labels.

The first step is to license your GTIN with GS1. Your next step to getting your product into the supply chain is placing your barcode on your actual product. Getting your product to go “beep” at checkout requires your packaging to follow a few simple rules about color, placement, and size.

Fun fact: On June 26, 1974, in a Marsh supermarket located in Ohio, a pack of Wrigley’s gum became the first product in the world to be scanned with a barcode.

Why Colors Matter

Colors of the barcode backgrounds impact the ability to scan the barcode properly; therefore, you need to consider the placement of the barcode as that may influence color selections. The most common barcode is the iconic black bars and white background (spaces and quiet zones) for a reason, it’s easy for retail checkout to read. However, these colors don’t work for every product on the market, so there are guidelines to follow when choosing the colors of your barcode.

• GS1 barcodes require high contrast for the bars in contrast to a lighter background. Think black, dark blue, or dark green for printing bars.  
• Scanners use red light spectrum so it is recommended to avoid printing bars in colors such as reds, pinks, and browns on your bars to prevent the scanner from missing or misreading them, but your background can contain these colors.
• Choosing a single-color ink for the barcode works best for scanners to read.
• Backgrounds are not typically printed, as they are the same color as the packaging. If you do need to print a background, make sure to use multiple layers of ink to increase opacity and fill any voids.

Placing Your Barcodes Correctly

Where you place your barcode on the packaging affects both the products’ movement throughout the supply chain and the end user’s experience. For barcodes scanned at checkout, you’ll want to consider things like packaging shape. Barcodes can be placed horizontally, with the bars running like a picket fence, or vertically, with the bars running like a ladder, it’s up to you to decide which works best depending on the space on the item.

For example, boxes with flat surfaces can use a horizontally placed barcode but when your product is cylindrical with a small radius, like a tube of lipstick, a vertically placed barcode would be best. Barcodes need to be placed on smooth, continuous surfaces so make sure to steer clear of bumpy packaging or getting too close to the edge of your packaging.

Size for Scanners

Due to the uniqueness of a GS1 barcode, the bars and background are designed with a fixed relationship between the length and width. As you adjust one measurement, an equal adjustment must be made of the other to maintain the readability. Things like truncating the barcode (removing portions) or printing graphics or text too close to the edge of the barcode (in the quiet zones) can create an incorrect scan. Create your barcode art in the size you’ll need for your packaging. If you need to change the size of the barcode art, do not shrink or enlarge it - it may not scan correctly. If you need to resize the barcode art, just re-create the barcode in the desired size.

When designing your barcode, it is important to allow adequate space for the barcode to be printed on the item to prevent errors at check out.
